Abstract:
The effects of four extraction parameters on the ginkgolides and bilobalide yield were optimized by taking Ginkgo biloba leaves as material，using ethanol-water extraction，single factor test.The ethanol concentration，extraction time，the ratio of solid-liquid and extraction temperature on the content of ginkgolides and bilobalide were studied.The extraction process was optimized.The results showed that the optimal extraction conditions were as follows,under the condition of the ratio of solid-liquid 1∶150 g?mL-1，extraction temperature 60 ℃，extracting 2.0 hours with 60% ethanol.Petroleum ether∶ethyl acetate =2∶1(v/v).By the analysis of HPLC-ELSD，the extraction rate was high，simple，with credibility.
